I made my son and husband felted slippers from the Fiber Trends pattern. I threw them in the washer and got called away by my sons (2 and 5months). One thing led to another and I didn't think about the slippers until everyone was in bed. My son's are just about perfect. My husbands are a tad small...okay, they fit me...I don't need slippers and I cannot afford another 4 hanks of 220 to make him another pair. If I wet the slippers and stretch them will I do them any harm?
